I just set up an Ubuntu Server and configured it via SSH using openssh on the server. I had to restart and cannot connect via SSH due to
Write failed: Broken pipe error.
As far as my research goes (https://wiki.archlinux.org/index.php/SFTP_chroot - Troubleshooting, first entry), that's an issue with ownership problem with the ChrootDirectory. I likely messed something up while setting up the apache webserver.
Anyway, now I cannot login via SSH with my username. Unfortunatelly, I only have one user so I can't use a different one. Is there any way for me to fix ownership or the openssh settings without physical access to the server? Thanks!
Trying to connect with debug options shows:
